Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery, specifically to a hot pressing mold for convenient material unloading. Background Technology
[0002] In agricultural machinery production, there are often thick U-shaped stamped parts that require hot pressing to achieve the desired shape due to their thickness. Currently, hot pressing mechanisms are used for this process. These mechanisms mainly consist of a fixed die and a movable die. The fixed die has a U-shaped cavity, and the movable die works in conjunction with this cavity to hot press the U-shaped part. However, during hot pressing, the heat from the workpiece is transferred to the movable die, causing the workpiece to shrink and often become stuck, making it difficult to eject. To address this, current methods often involve an upper ejector mechanism or directly striking the workpiece to remove it. Upper ejector mechanisms are complex, have high manufacturing and maintenance costs, and a high failure rate. Directly striking the workpiece can damage its appearance and is inefficient. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a convenient hot pressing mold for unloading materials, which facilitates the peeling of workpieces during hot pressing.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a convenient hot pressing mold for unloading, including a fixed mold, a movable mold, and an unloading component. The fixed mold is provided with a mold cavity, and the unloading component is located on one side of the cavity opening. The unloading component is provided with an unloading end face, and an avoidance channel is provided on the unloading end face corresponding to the cavity opening. The movable mold passes through the avoidance channel and moves between the hot pressing position and the standby position. When the movable mold is in the hot pressing position, it extends into the mold cavity and cooperates with the mold cavity to hot press the product. When the movable mold moves from the hot pressing position to the standby position, the unloading end face peels the product off the movable mold. After hot pressing, the movable mold moves from the hot pressing position to the standby position. During the movement of the movable mold, the product stuck on the movable mold due to shrinkage comes into contact with the unloading component and is peeled off by the unloading component, thus achieving unloading.
[0005] As an optional technical solution, the blanking component includes a first hook and a second hook. The first hook and the second hook are connected to the fixed mold. The first hook and the second hook are symmetrically arranged on both sides of the mold cavity opening, and the gap reserved between the first hook and the second hook forms an avoidance channel. Both the first hook and the second hook are provided with blanking end faces.
[0006] As an optional technical solution, both the first and second hooks are hook structures. The hook structure includes a connecting part and a blanking part. The connecting part is connected to the fixed mold, and the blanking part is set on the connecting part. The blanking part is located on the side of the connecting part near the mold cavity opening and forms an L-shaped structure with the connecting part. The end face of the blanking part facing the fixed mold is set as the blanking end face. There is a clearance channel between the blanking parts of the first and second hooks.
[0007] As an optional technical solution, the mold cavity is a U-shaped cavity, and there are at least two blanking parts distributed along the long side of the mold cavity. The cooperation of multiple blanking parts ensures that the product is subjected to uniform force and avoids affecting the product's appearance.
[0008] As an optional technical solution, a replaceable inner mold is provided inside the mold cavity.
[0009] As an optional technical solution, the inner mold is a U-shaped mold formed by splicing two L-shaped molds.
[0010] Compared with the prior art, the present invention has the following advantages: the hot pressing mold of the present invention has the advantages of low cost, simplicity and reliability, which helps to improve the efficiency of hot pressing of U-shaped thick plates. Compared with the original molds of the same kind, the product can be quickly peeled off after hot pressing through the blanking part, realizing demolding and blanking, which helps to reduce the labor intensity of personnel.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0014] like Figure 1 and Figure 2As shown, a convenient hot press mold for unloading materials includes a fixed mold 1, a movable mold 2, and an unloading component 3. The fixed mold 1 is provided with a mold cavity 11, and the blanking component 3 is provided on one side of the cavity opening of the mold cavity 11. The blanking component 3 has a blanking end face 33 on the end face facing the cavity opening of the mold cavity 11. The blanking end face 33 is provided with a clearance channel for the movable mold 2 to pass through at the cavity opening of the mold cavity 11. The movable mold 2 is provided with a power connection part for connecting with the moving part of the hot pressing drive. Driven by the hot pressing drive, the movable mold 2 passes through the clearance channel and moves between the hot pressing position and the standby position. When the movable mold 2 is in the hot pressing position, the movable mold 2 extends into the mold cavity 11 and cooperates with the inner wall of the mold cavity 11 to hot press the product. During the hot pressing process, the heat is transferred to the movable mold 2, causing the product to shrink and get stuck on the movable mold 2. After the hot pressing process is completed, as the movable mold 2 moves from the hot pressing position to the standby position, the blanking end face 33 of the blanking component 3 abuts against the product stuck on the movable mold 2, and peels the product off the movable mold 2 as the movable mold 2 moves, thus realizing blanking.
[0015] When hot pressing products using the hot pressing mold of this embodiment, the hot-pressed product is placed in the mold cavity 11. The hot pressing drive component drives the movable mold 2 to pass through the clearance channel and move towards the mold cavity 11. The movable mold 2 cooperates with the fixed mold 1 to hot press the product in the mold cavity 11. After hot pressing, the hot pressing drive component drives the movable mold 2 to detach from the mold cavity 11. When passing through the clearance channel, the product stuck on the movable mold 2 is peeled off due to the obstruction of the unloading component 3.
[0016] Please see Figure 1 A space should be reserved on the side between the blanking end face 33 and the cavity opening of the mold cavity 11 to facilitate the loading of the product to be hot-pressed into the mold cavity 11 and the removal of the hot-pressed product from the fixed mold 1.
[0017] Please see Figure 1 and Figure 2 The material dropping component 3 includes a first hook 31 and a second hook 32. Both the first hook 31 and the second hook 32 are connected to the fixed mold 1. The first hook 31 and the second hook 32 are symmetrically arranged on both sides of the cavity opening of the mold cavity 11, and the gap reserved between them forms an avoidance channel. Both the first hook 31 and the second hook 32 are provided with a material dropping end face 33.
[0018] The first hook 31 and the second hook 32 are hook structures, each including a connecting part and a blanking part. The connecting part is connected to the fixed mold 1, and the blanking part is provided on the connecting part. The blanking part is located on the side of the connecting part near the cavity opening of the mold cavity 11, and the blanking part and the connecting part form an L-shape. The end face of the blanking part facing the fixed mold 1 is set as the blanking end face 33. The gap between the blanking part of the first hook 31 and the blanking part of the second hook 32 is a clearance channel.
[0019] When the movable mold 2 moves from the hot pressing position to the standby position, the movable mold 2 passes through the clearance channel between the first hook 31 and the second hook 32. When the product stuck on the movable mold 2 comes into contact with the material dropping part of the first hook 31 and the second hook 32, as the movable mold 2 moves, the product is blocked by the first hook 31 and the second hook 32 and detaches from the movable mold 2.
[0020] Please see Figure 1 The fixed mold 1 is a U-shaped block, and the mold cavity 11 is a U-shaped cavity set on the upper end face of the fixed mold 1. Two or more blanking parts 3 are set and arranged along the long side of the mold cavity 11, so that the workpiece can be subjected to a relatively uniform force when blanking. Of course, the blanking part 3 can also be set as one. In this case, the blanking part of the first hook 31 and the second hook 32 is a long strip along the long side of the mold cavity 11, which can also make the workpiece subjected to a relatively uniform force when blanking.
[0021] Please see Figure 1 and Figure 2 As an optional implementation, an inner membrane is provided inside the mold cavity 11. During hot pressing, the movable mold 2 cooperates with the inner forming cavity of the inner mold 12. The inner membrane is detachable to accommodate hot pressing of products of various specifications. The inner membrane includes two L-shaped molds, which are spliced together to form a U-shaped mold.
